I don't really see whats interesting about this either way. Lots of places you interview at tell you what the interview is going to be like and what you are expected to be familiar with. This is just 'write code and we'll be testing you on data structures and algorithms!'

There's some flowery language there about having a genuine desire to want to hire you unlike those 'other evil companies!'... sounds like the same shit pretty much every other company does to me.
